Brandon Waring hit a two-out homer in the ninth off Troy Patton to knot the score. Patton will serve a 25-game suspension at the start of the season after a positive test for a banned amphetamine.

Chen gave up one run, walked one and struck out three. He’s got a 2.00 ERA in three outings this spring training.

Tommy Hunter, poised to take over for Jim Johnson as Baltimore’s closer, worked a perfect fifth inning with a strikeout. The only two runs he’s allowed in four innings came on solo home runs by Boston’s Will Middlebrooks.

The Orioles used two singles and a walk to load the bases with no outs in the second against Mike Pelfrey but got only one run, on a sacrifice fly by Quintin Berry.

“I would prefer not to be in those situations, but they’re definitely going to happen and I thought that was good damage control,” Pelfrey said.

In the bottom half, Eduardo Escobar hit an RBI single. Urrutia homered in the fifth off Brian Duensing.

STARTING TIME

Orioles: Chen said he’s on target for the start of the regular season.

“I think everything is on pace according to the plan,” the left-hander said through an interpreter. “Maybe some of my off-speed offerings I need to work on for a little bit. But everything else is in place for getting ready for the opening series.”

Manager Buck Showalter said: “”He’s in a good spot. Hopefully he can take this and build on it. He was scheduled for 60 pitches, and we had him 60 on the button. Just what the doctor ordered.”

Twins: Pelfrey allowed one run, five hits and one lamentable walk in 3 1-3 innings.

“The one thing that maybe irritated me more than anything was the (Nolan) Reimold at-bat, when I got ahead and tried to throw some sliders and got into a full count and walked him,” Pelfrey said.

The walk, sandwiched between two singles, led to Baltimore’s only run off the right-hander.

Pelfrey likes where he stands just over two weeks before the opener.

“I have three more starts and I want to take advantage of that,” he said. “I feel like there’s still some arm strength to build up, but I feel good about where I’m at right now.”
